which would affect alignment, and in a manner to securely Atie the saidmembers of thc frame together. n

An object of the present invention is to provide a support for theengine upon the frame, which support is such as to positively obviateall metal to metal Contact between engine and trame, thereby eliminatingthe transn'iission ot any engine vibration to the Jframe through anymetal path. A further obje-et is to so construct such a support as toprovide a strong construct-ion embodying yieldable material so arrangedand confined as to obviate disintegration and provide a positiveconnection between the supported and the supporting members of thedevice, at vthe same time` preferably providing an arrangement wherebymay be secured a difference in the. cushioning of the different relatire movements between the part-s and, further. provide an arrangementwhereby this difference in cushioning action may be readil).Y secured orquickly adjusted. It is also an object to so construct the device thatthe parts may be made at a minimum cost. by the use of duplicate partsand assembly and replacement facilitated;I and to so construct thesupport that the side members of the chassis trame are positively tiedtogether' by the engine frame without forming a metal to metal contar-tpath. and -a velv strong and rigid device. simple in construction andcheap to 5 manufzu-ture. is provided for suspending the engine from thechassis frame.

I With the above and other ends in View, the invention resides in thematters hereinafter set forth and morel particularly pointed out in theappended claims, reference being had to the accompanying drawings inWhich- Figure 1 is a vertical section of the device embodying thepresent invention, substantially upon the lines 1-1 of Figures Qcand 4;

In the construction illustrated in Figures 1 to 4 inclusive of theaccompanying drawings, 1 indicates one ot the side channel members ofthe chassis frame of a motor vehicle between which channel members theengine is usually supported upon saidmembers by laterally extending armsusually cast integral with the engine base', the end portion of one ofsaid engine arms being indicated as a whole, by the numeral 2. It is theusual practice to secure Within the channel member 1 some. form ofbracket and to secure the ends 2 of the engine arms to these bracketsprojecting from the channel frame. members with the engine thussuspended Within the chassis frame between these side channels which arethustied together by the engine base. When the engine arms are directlyattached or otherwise connected to such brackets by bolts or other metalconnections, vibration set up by engine operation is transmitted by thismetal-path` to the chassis frame, and this is true even Where springs orother cushioning means is employed to yieldingly mount the gpgine uponor suspend it from the chassis ame.

In the present construction metal to metal contact forming a path fromengine to frame which would transmit such vibrations, is entirelyeliminated, blocks or pieces formedvof a yielding rubber orsimilarfcomposition being interposed and held in such a manner that nobolts or other connections can form such path. I

This support includes a bracket 3 of any desired configuration butpreferably comprising two strips of sheet metal of U-shape in planv`view and with one lying within the other to provide strength andrigidity, the ends 4 of the front and rear side walls 5 `being turnedlaterally to provide places of rigid attachment of the bracket withipthe channel 1, and these side Walls being con nected by top Walls G toform a rigid box-like structure having a vertical end wall 7 for theattachment thereto and support of the end of the motor arm 2, the twoplates forming the end wall 7 being spaced at their upper ends from thecross plates G and these pl .tes of the end wall being turned laterallyin opposite directions along their lower edges as at 8, providingbottoml supporting flanges on this end wall of the bracket.

Applied to both inner and outer-sides of wall 7 and seated at theirlower` ends upon the flanges 8, are blocks or strips 9 of resilientmaterial such as rubber, and these resilient blocks or sheets are firmlysecured to the inner and outer faces of the end wall 7 of the bracket bypunching vertical rows of spaced apart holes 10 in each plate formingsaid end wall and forming a flange 11 around each hole, which flanges onone plate project laterally therefrom into corresponding holes in one ofthe rubber blocks andthe flanges on the other plate, into holes formedin the rubber block against the other side of the bracket wall 7, theserubber'facings or blocks being thus firmly connected to the bracket Walland supported against movement thereon by these flanges and by theflanges 8 engaging therebeneath.

A yoke or loop is formed of two metal strips or plates 12 and 13 toenclose the rubber blocks 9 with the bracket end wall 7 between them,these plates being formed or bent toward each other attheir upper landlower ends to extend over the upper and lower ends of the blocks and endwall of the bracket where they meet with their ends vturned outwardlyforming end f'langes 14 on the loop or yoke which are secured togetherby rivets 15. The metal loop thus formed by these strips or plates 12and 13, embraces and clamps the rubber blocks between them, contactingthe sides and upper ends of said blocks only, and held out of contactwith the bracket wall by said blocks, the fianges 11 around the openings10 in the plates 'forming the end wall 7 of the bracket, being of lesserlength than the thickness of the blocks so that they do not come incontact with the plates 12 and 13. The rubber blocks thereforecompletely insulate the bracket from this metal supporting loop whilethe blocks are held firmly in place upon the inner and ppter vsides ofthe bracket wall, by the flanges To attach the arms 2 on the engine tothese metal loops or to the bracket so that the cngine will lbesuspended between the channel frame members 1, each loop is rigidlysecured to the end of each arm 2 by means of bolts 16 having rectangularheads 17 within the loops with their shanks extending through holes inthe plate 12 of the loop and through holes in the end of the arm 2, nuts18 and lock washers 19 being applied to the shank ends to draw up vthebolts and firmly and rig idly secure the plate 12 of the loop againstthe end face of the arm. The heads 17 of these bolts are of lesserthickness than the block 9 which is formed with openings to receivethese heads and therefore said blocks completely insulate these boltsfrom the supporting bracket on the chassis frame, and the whole weightof the motor is taken by the rubber insulating blocks through the plates12 and 13 which embrace the blocks and are completely insulated by saidblocks from said bracket.

lTo provide a firm connection between each of the plates 12 and 13 andthe rubber blocks 9 with which the are in contact throughout their faceareas, anges 20 are struck inwardly of the loop from openings in saidplates, the blocks 9 being formed with openings to receive said flangeswhich are of lesser length than the thickness of the blocks which theyengage so that these flanges will not come into contact with the wall 7of the bracket, and these flanged holes are arranged in staggeredrelationto the flange holes 10 in the -plates forming the end wall 7 ofthe bracket,

the holes along the vertical side edges of the plates 12 and 13 beinghalf holes provided with half flanges and all of the holes and theirflanges in both plates 12 and 13 and those in the lates ormin the endwall 7 of the bracket, Ibeing prefera ly of rectangular form andarranged angularly wit-hin the platesf so that thebodies of the rubberblocks between Vthe several flanges will he subjected to evencompression and strains throughout their entire areas while being heldin place by these anges, relative to said plates and bracket Wall.

With this construction and arrangement there is no metal to metalcontact between parts carried by the chassis frame and parts carried bythe engine, and, therefore, vibrations set up by engine operation willnot be transmitted to the frame but will be dampened by the rubbercomposition insulating yielding movement of engine relative to frame dueto the limited compression of these blocks over the entire arca of cachduc to the staggered relation of the several flanges off the openings inboth plates of the supporting loop and in the plates forming the endsupporting wall of the bracket, said flanges being distributed over theentire areas of these plates and all projecting laterally ltherefrominto openings in the interposed yieldable blocks.

As the engine arms are rigidly secured to the supporting loops whichembrace the end supporting Walls of the brackets on the chassis framewith the rubber blocks interposed, the side channel chassis framemembers l are securely tied together without the formation of metal tometal contact paths which would transmit vibrations from engine tochassis frame and the engine is yieldingly suspended from the frame, theinsulating blocks'providing for a limited relative movement whilesupporting the entire load of the engine..

In Figures 5 to 9 inclusive of the accompanying .(li'awings, asimplified construction -is shown and a construction which is lessexpensive to manufacture, and in some respects, more eflicient inoperation, it having certain advantages, such as certain interchangeableand yeasily replaceable parts and an arrangement whereby a differentcushioning effect of the relative movement of the parts in one directionmay be secured over the cushioning effect of the relative movement ofthe parts -in another direction, as hereinafter more fully set forth.

In Figures 5, G and 7, the chassis chan-v nel frame is indicated by thenumeral 21 and the end portion of the engine supporting arm, by 22. Thebracket 23 may be formed from a single strip of metal bent into U-formin plan view with its ends turned outwardly to provide ears 24 forsecuring the bracket withing the channel of the frame as shown, but

obviously this bracket may be constructed thc same as shown in Figs. land 4 if found desirable for the purpose of strength and rigidity, orsaid bracket may be secured to the end of the engine arm` and the'loopor yoke member secured Within the channel of the frame member 2l wheresaid channel is sulliciently deep to take said yoke, if found desirable.

The inner end Wall 25 of the bracket is formed with two vertical,parallel rows of being in the form of an angle bar, and each end of thewall 28 is turned at right angles forming end lugs 3l. Each of theseangle bars is also bent laterally intermediate its ends toward theflange 30 so that said bar in the direction of its length will conformto the inclination of the slots 26 in the wall 25 and bring its lugs 27into position to engage in said slots, with one angle bar lying with itswall 2S flat against the surface of the wall 25 and another like barlying flat against the opposite side of said wall with the lugs 2i' onboth bars engaged within the same slots 2G in the bracket wall. i

rl`o provide a yoke or loop to embrace the end wall 25 of the bracketand for attachment to the end of the motor arm 22 so that said arm willbe. connected to and supported by said bracket.` a pair of plates 232and corresponding to the plates 12 and 13 of the construction shown inFigures l to 4, is provided, the end portions of these plates beingofl'set laterally to together form al1 end wall ill for cach end of theloop or yoke, thus formed by said plates 32 and 33, the ends of .theseplates being again turned at'right angles to provide ears 35 by means ofwhich the plates may be permanently secured togcther with the walls 32and 33 spaced apart a distance equal to the oil'sets therein which formthe end walls 3l of the loop, these ears being secured together byrivets 36 passing through openings therein. 'lhe plate or wall .232 isformed with lateral extending portions which provide ears 37 formed withopenings to receive bolts 38 for securing the loop or yoke forlned bythese plates, rigidly Ato the end of the motor arm 22. l

The walls 32 and 33 of the loop are each formed with vertical rows ofslots 39 corresponding to the slots 26 in the bracket wall 25 in sizeand direction of inclination but arranged intermediate. said slots 26 sothat they will be in proper place to receive the lugs 2T on angle bars2i) placed intermediate those bars, the lugs on which are engaged withthe slots in bracket wall 25. The space at each side of the plate 25Within the loop or yoke, is thus divided into channels extendingtransversely of the loop by a vseries of angle. bars all of the sameconstruction but connected alternately to the wall V25 and to the. walls32 and 33 of the loop by means of the lugs 27 on these bars engaging theslots 2G in tlieplate 25 and the slots 3S) in the plates 32 and 33, thefiange 3U on cach of the bars connected to the bracket wall 25 extendinglaterally from the faces of said wall to within a short distance. of theinner faces of the yoke walls, and the flanges El() on the. barsconnected to the loop Walls, extending inwardly therefrom to near thefaces of the bracket Wall. These channels thus formed between saidflanges on adjacent bars, are. substantially rectangular in crosssection but extend laterally and upwardly in an inclined direction fromthe central bend in each bar, and the ends of these channels aresubstantially closed at their ends by the end ianges or lugs 31 ou theseveral bars.

Strips or blocks 40, one of which is shown in perspective in Figure 8,are formed of yieldable resilient material, such as rubber composition,and of a size and shape to accurately fill the 'several channels formedbetween the flanges 30 of the several bars and the inner faces of theseveral walls 28 of said barsand the faces of the bracket wall 25 andalso the inner faces of the yoke or loop walls. Each rubber block 40 isthus securely confined in place within the .yoke between it and thebracket wall, and, together these blocks insulate said bracket wall fromthe yoke walls so that there is no possibility of a metal contact whichwould transmit vibration from yoke' to bracket and yet the enginesupporting arm is securely attached to the frame bracket and heldagainst movement relative thereto in any direction, with the exceptionof the very slight relative' movement afforded by the slight yield ofthe several rubber blocks which will be made to prevent such yield aswould allow the opposed angle bars 29 to contact each other.

As certain of the angle barsv 29 are connected by their lugs to the loopor yoke walls, and the other bars are connected to the bracket wall,engine load tending to move the loop downwardly will be resisted by theseveral blocks seated upon the flanges 30 of the bars connected to thebracket wall, as will also be any torque or twisting strains, theseveral blocksl being compressed transversely by said twisting movementas well as longitudinally, due to the relative angular relation of theend portions of each block or bend`therein. A great advantage in the useof a plurality of separate insulating blocks or strips over the use oftwo continuous pieces or strips9 as shown in Figures l to 3, is thatsome of the blocks 40 may be formed from a different composition thanothers so that they will not all offer the same resistance tocompression and therefore, if it be desirable to provide les resistanceto compression of the rubber upon the up movement of the loop-supportfor the engine, than upon the down movement of the loop under engineload, this difference may be provided by making those blocks which are'compressed-by up movement of the loop relative to the bracket wall ofgreater yieldabgility than those blocks which take the load in theopposite direction. Any desired variation in cushioning effect maytherefore be secured by modifying the resiliency'of certain blocks.

A very desirable feature of the construction shown in Figures 5 to 9 isthat all of the angle bars 29 are exactly alike, a single stamping, thusgreatly facilitating and cheapening manufacture, and as these bars areall securely confined within the engine supporting loop or yoke therewill be no appreciable wear either of these bars or of the blocks 4()and none of the parts can get out of place or become broken in use.

The present construction provides a support and connection which ischeap to manufacture, being principally formed of sheet metal stampins,and which construction is such that the yieldable blocks of rubbercomposition are thoroughly protected against disintegration, the rubberbeingr so confined and engaged by the relatively movablemembers as toevenly distribute compression thereof, and the connection of theserelatively movable parts to the blocks is positive and permanent, suchconnection heilig mechanical rather than by a vulcanizing of the rubberinto connection with the metal parts.

Obviously changes may be made in the construction, arrangement andcombination of parts, within the scope of the appended claims withoutdeparting from the spirit of the invention, and such changes arecontemplated.

Having thus fully described my invention, what I claim is l. In a motorsupport, the combination of a bracket having an end wall, a supportingmember connected to said bracket and having a wall spaced from saidbracket wall, a plurality of like members in said space between saidWalls, certain of said members being connected to said bracket wall tomove therewith and other of said members being connected to saidsupporting member wall to move therewith, said members beinginterchangeable, and resilient blocks in said space between said bracketwall and said wall of said supporting member and between adjacentmembers in saidspace, said blocks being arranged to preventiinetal tometal contact between said bracket and supporting member and betweensaid members in said space.
